Flange 34 also has one group of radially keyway or breach 30b, and they hold the other end of key 31, like that just shearing drum 15 or 16 are latched on the sleeve 28.

Also have a circle or loop section 35 to be positioned at the top of grooved bearing 32, be connected to each other with pair of screws 36 in order to the cylinder-shaped

end

33,32 and 35 parts of pinning shearing drum 15 and 16.

The other end Bei Zhi Cheng And on shearing drum 15,16 opposites is contained on the screw element 38, a nut 39 that is used for axial locking is arranged on the cylinder 15,16 of shearing elements (not shown), it rotates by means of the effect of vertical feather key 55; And ends up with coaxial, a undersized cylinder-shaped end 40, it be suitable for being placed in the very similar grooved bearing 41 of cast part 32 on, bearing 41 is arranged on the idle running sleeve 42 Shang ， And that stretch out from stand 14 bodies the end and the sleeve 28 of stand 13 is axially aligned.

Also be in this case, another cast part 43 can like that just be latched in column part 40 on the idle running sleeve 42 by means of screw (not shown) and the combination of grooved bearing.

Be provided with the device of mobile stand in the inside of base 12, it is made up of a pair of drive screw 44 and 45, act on their end 47 and 48 selectively by means of a crank 46, stand is traversing on base 12, and screw rod 44 and 45 is nut 49 and 50 engagements inner and that join together with the bottom of two stands 13,14 at base.

Stand 13 and 14 just can be moved by said transmission device like this, moves independently of one another in the indicated direction of arrow 51, and moving direction is perpendicular to passing cylinder 15 Hes

The flat board of wanting roller shear between 16 or the direction of motion ， And of band allow shearing drum to be installed on the different workbench according to interim needs.

Intermediate transverse girder 52 also is equipped with in these external base 12 inside, and is corresponding with it, determined that one shears the axis of symmetry 53, And and stand 13 and 14 is moved by the slip along the guide rail 54 of base 12 tops with respect to shearing the axis of symmetry.

Intermediate transverse girder 52 and both sides crossbeam 56 and 57 all are installed on the base 12 together, and drive screw 44 and 45 end are rotatably supported on the crossbeam, so that mobile stand.

The machine of making by the present invention, in case want the width of the metal tape of roller shear to be determined, shearing drum is Dinged And with regard to Bei Xuan and is ready to accordingly.

More precisely, a whole set of blade and conjugation blade (not shown) are positioned on mandrel 15 and 16, make their engagement And and under mandrel 15 and 16 static states by means of vertical feather key 55, be locked on their operating position, described blade one side leans against on the flange 34 opposite side, by screwing the nut 39 on the screw element 38, and fasten them.

Ready in a manner described shearing mandrel or cylinder 15 and 16 are installed between stand 13 and 14, they be contained in grooved bearing 32 and 41 above, shear mandrel and in the operational phase, supported by them.

In the middle of this process, stand 13 and 14 has been so positioned, so that can be enough correct means and almost be under the condition of careful adjustment are held shearing drum 15 and 16.

During a kind of like this location, by shearing drum 15 and 16 is rotated on grooved bearing 32 and 41, and groove 30b on the flange 34 is placed on the corresponding to position of groove 30a with flange 29, to realize the desired location to used shearing elements.This result is linear for not possessing, the location particular importance of the shearing elements in different shape cross section, by doing like this, in fact, guaranteed the complete matching between the cross section of last shearing elements and down cut element, under any circumstance, can both avoid their blade to overlap each other.

Then, ring 35 and be that key 31 is all loaded onto at last, and key 31 makes the motion of rotatablely moving of sleeve 28 and shearing drum 15 and 16 in full accord.

This clearly encircles 43 and also has been placed in the top of grooved bearing 41, so also barrel portion 40 is constrained on the idle running sleeve 42.

Shearing drum 15 and 16 this fast and be easy to the location and can accurately accomplish, because being used for of making the machine of continuous band roller shear slivering is had a direct dual adjustment by the present invention, be that vertical range between the shearing drum center has convertibility, it is the function of diameter of cylinder, also is the function of shearing elements diameter; And the bearing headstock has relative mobility with respect to a shearing axis of symmetry, can move independently of one another.

In fact, by starting variable-speed motor (it causes fluted shaft 25 rotations and then is the motion of speed changer 37), motion is reached four deceleration devices 24, and they are positioned on the pedestal of stand 13 and 14 by twos.

Rotational motion is passed the threaded bar portion to screw rod 23 then, 23a has left hand thread, and 23b has right-handed thread, in the nut 22 that links, require bearing 20 vertically to move with respect to bearing 21, for example be moved away from each other on the direction of the arrow in Fig. 1 58, until the position that reaches big opening, this aperture position is with respect to representing with chain-dotted line among the band that will shear central horizontal axis 59(that will pass through and the processed figure).

In this case, for the continuity of the acceptance that rotatablely moves that drives to shearing drum 15 and 16, owing to there being epicycloid joint 17 to be guaranteed, because the same nature of joint, they automatically accurately and the different distance between each centre of the drum match, as Fig. 5 to shown in Figure 8.

A kind of so mobile importance is the device that can provide suitable, because the shearing drum or the mandrel of band shearing elements have variable external diameter.In the variation of diametrically,, also be because the development in the non-linear cross section in cross section more or less some bending of blade or sinusoidal is caused except being the difference owing to the band of wanting roller shear.

In case the selection of shearing drum 15 and 16 is finished, and bearing 20 and 21(are supporting cylinder 15 and 16) relative position fixing, stand 13 and 14 move just can be by crank 46 or also can be undertaken by the suitable drive mechanism (not shown), this drive unit and base 12 join together, connect with drive screw 44 and 45.

This causes nut 49 and/or 50 with respect to screw rod 44 and/or 45 and slide, and then is moved with stand 13 and/or 14 that above-mentioned nut joins together.

Need the special structure and the result of location as crossbeam 52,56 and 57, if cylinder has to be installed in respect to shearing on the position that the axis of symmetry 53 is not exclusively symmetries, the moving of any independent stand in 13 or 14 also can be realized.

This adjustment of stand also need not be dismantled any support or be more preferably without the teardown of engine and just can be finished, and only needs to take off cylinder.

In addition, a kind of like this mechanism brings very big superiority, and it also can overcome the influence of presumable play or mispointing at least partially, makes that the installation of shearing drum is easier and faster.

In addition, device can also for overcome following among both presumable play create conditions, i.e. between the main gear down device that play in shearing drum or the mandrel, and stand and transmission are rotated in conjunction with the play in the joint; At last, can also overcome at the play that drives in nut 22-screw rod 23 transmissions of bearing 20,21.
